LCD-X Magnetic Flexible Ceramic Heaters

The LCD-X Magnetic Flexible Ceramic Heater is an advanced engineering solution specifically designed for weld preheating and post-weld heat treatment (PWHT) of large metallic structures. Unlike conventional heaters, this model integrates powerful steel magnets into its structure, enabling instantaneous adsorption onto ferrous surfaces without the need for bolts, straps, or complex mechanical fastening systems. Its crawler-type design grants it exceptional flexibility, allowing the heating element to perfectly conform to the curvature of tanks, gas spheres, ship hulls, and large-diameter pipes, ensuring uniform and efficient heat transfer.

The LCD-X Adsorption Heater represents the evolution of industrial thermal blankets. This equipment combines the durability of high-alumina ceramic elements with the practicality of magnetic fixation, drastically optimizing on-site setup times. It is the core component of a professional heat treatment system, designed to work in conjunction with intelligent temperature control units. Its ability to maintain intimate contact with the workpiece reduces thermal losses and enhances operational safety, making it the preferred tool for quality inspectors and welding technicians seeking to comply with international standards for thermal stress relief.

The LCD-X Magnetic Heaters are indispensable in sectors where weld integrity is critical:

Sector

Specific Use

Shipbuilding

Preheating of steel plates in ship hulls and deck structures.

Pressure Vessels

Heat treatment in gas storage spheres, LNG tanks, and industrial boilers.

Heavy Infrastructure

Heating of bridge girders, wind towers, and thick steel structures.

Petrochemical Industry

Maintenance of process pipes and reactors requiring precise thermal control.

Specialized Welding

Prevention of hydrogen-induced cracking and reduction of thermal gradients in alloy steels.

 

  • Instant Magnetic Fixation:​ The integrated magnets eliminate the need for welding attachment bolts, protecting the integrity of the workpiece surface.

  • Multidirectional Flexibility:​ Its articulated structure allows bending on multiple axes, adapting to complex geometries and tight radii of curvature.

  • High Thermal Resistance:​ Manufactured with high-purity alumina ceramic and long-lasting Ni-Cr alloy cables, capable of withstanding intense thermal cycles.

  • Uniform Heat Distribution:​ The optimized design of the ceramic blocks ensures no cold spots, guaranteeing homogeneous heat treatment.

  • Voltage Versatility:​ Available in 220V and 110V configurations to adapt to different power sources and control boxes.

  • Setup Time Reduction:​ The adsorption system reduces preparation time by up to 70% compared to traditional fixation methods.

To ensure optimal and safe operation of the LCD-X Heaters, strictly follow these guidelines:

  1. Surface Preparation:​ Ensure the contact area is free of loose rust, oil, or flammable paint to guarantee firm magnetic adsorption and efficient heat transfer.

  2. Grounding Connection:​ The metallic component or workpiece must have a reliable ground connection before starting the heating process.

  3. Heater Installation:​ Attach the magnetic heater to the workpiece. Do not allow the heaters to overlap or overlay each other during use, as this will cause local overheating and damage the element.

  4. Temperature Monitoring:​ The thermocouple (temperature sensor) must be firmly attached to the workpiece surface, preferably via capacitive discharge welding or direct mechanical contact under the heater.

  5. Thermal Insulation:​ Cover the heater with rock wool or aluminium silicate blanket to prevent heat dissipation to the environment and protect personnel from accidental burns.

  6. Removal:​ Do not remove the heater while it is at maximum power. Wait for the temperature to drop to safe levels before handling the magnets.

FAQ

The high-power magnets integrated into the flexible ceramic heaters are designed to maintain their holding capacity within safe operating ranges. However, it is vital to consider these technical limits:
Safe working temperature:​ The magnets effectively maintain their full holding capacity up to 300°C - 350°C.
Critical limit:​ If the contact surface exceeds 450°C, the magnets permanently lose their strength (Curie point).
Recommendation:​ For stress relief (PWHT) processes exceeding 600°C, it is recommended to contact the manufacturer for special configurations or to remove the magnets once the blanket is mechanically secured if the heat will be excessive.
